Brown ground beef in a skillet and drain the grease off. Add in the refried beans, taco seasoning and salsa. Cook for 5 minutes and remove from heat. In a 9 x 13 casserole dish spread 2 C. tortilla chips around the bottom.

Evenly spread the meat mixture over the top. Top that with 1 1/2 C. cheese, 1/2 the green onions and 1/2 of the chopped tomatoes.

Bake at 350 degrees for 20 minutes. Remove from oven and top with shredded lettuce, remaining green onions, tomatoes, a few more chips and then the remaining cheese.
